Freiburg will seek repeated wide deliveries against Union, while Vitória will change its block height against Porto's first progression. Each match has a meaningful second-ball contest after the opening attack. The late receivers and restarts should decide whether pressure becomes another clear finish.
Union's Rønnow, Friedrich and Khedira spine held Köln to few on-target attempts, and Burcu, Skarke and Haberer can carry the first pass beyond Freiburg's counterpress. Uduokhai and Nsoki are missing, while Ilic is only an optional bench contribution. Freiburg can add fresh forwards, but its recent wins relied on narrow finishing windows after the Trabzon trip. I'm siding with Union Berlin to hold the game close.
Vitória's recent visits to Gil Vicente and Benfica produced little clean final contact despite spells of territory. Porto can re-enter from the interior to the wing, then use Bednarek and Kiwior on corners or later attacking substitutions after a clearance. Pietuszewski's full capacity is uncertain, so that path is grounded in the players already carrying Porto's recent attacks. I'm siding with FC Porto to find the deciding contact.
